A fast power losses calculation method for long real time thermal simulation of IGBT module for a three-phase inverter system is presented in this paper. The speed-up is obtained by simplifying the representation of the three-phase inverter at the system modelling stage this allows a inverter system to be simulated predicting the effective voltages and(More)
This paper explores the use of a dynamic virtual impedance approach to load sharing as an alternative to the more generic droop load sharing scheme for low-voltage islanded micro-grids. The approach is based on taking advantage of the power decoupling capability of the virtual impedance scheme to facilitate appropriate load sharing based on the available(More)
In this paper, a predictive dead-beat proportional-integral (PI) current control algorithm is studied for shunt active power filters (APFs). To investigate the effectiveness of the proposed control scheme a digital control based simulation model is built using commercially available VisSim software. Performance comparison with different control schemes are(More)
